This plant was present in the backyard when my Mom bought her new house two years ago. I haven't been able to figure out what it is. It flowers all summer and produces what look like berries. My sister thought it might be an odd type of fuschia because the 'berries' resemble what they produce. The stems are probably more than 10' in lenght but they bend under their own weight and if it wasn't tied up it would spread out over the whole yard. Any ideas?
